TVA adding height to 4 dams in Tennessee


KNOXVILLE, Tenn. (AP) - The Tennessee Valley Authority is
completing temporary construction to raise the height of four dams
in Tennessee.
The Knoxville News Sentinel reported that over the next few
weeks, TVA will complete temporary work that will increase the
height of the Tellico, Watts Bar, Fort Loudoun and Cherokee dams.
The utility plans permanent construction later.
Chuck Bach, who heads river scheduling for TVA, said the utility
wouldn't be doing its job if it didn't prepare to lessen floods
coming down the Tennessee Valley.
Bach said the new work would prepare the dams for a "probable
maximum flood" - an event that would occur once in 700,000 to 1
million years.
